A new SRL with magnetic intelligence. Smarter retraction, smoother reaction.

Applying science to the safety of motion makes for a more intelligent approach to protection at heights. 3M studied how you work, move and interact with self-retracting lifelines to create 3M™ DBI-SALA® Smart Lock Self-Retracting Lifelines. See what they learned, and how they harnessed the science of safety to create fewer unintentional lockups. Make your work at heights easier and more productive with smarter retraction and smoother reaction.
